The Miami Heat briefly silenced Dallas fans Tuesday night in a last-second victory in game 3 of the best-of-seven series.

"Once I saw Shaq on the floor fighting for that rebound, I knew we were going to do it," said Miami City Manager Joe Arriola, who is one of the Heat's most vocal fans.

Before the game, Arriola and other Heat fans got riled up over a sign displayed by Maverick's owner Mark Cuban.

Cuban docked his yacht next to the American Airlines Arena and posted a large "Go Mavs" banner on the yacht.

"I got a call from the Heat about 3 o'clock, saying, 'You won't believe what this guy did,'" Arriola said. "I sent my folks out there and I was ready to go with Chief (John) Timoney to tear it down myself."

Miami police and code enforcement inspectors told Cuban if the sign didn't come down, the yacht would lose its permit to dock.

"They're not going to have the sign. They're not coming to our town and putting up the sign 'Go Mavs.' I don't know what's wrong with Mark Cuban, but we're not going to let him get away with that," Arriola said.
